摘 要：
】１９９１～１９９６年，从江苏省主要稻区采集到４９１份稻瘟病标样，单孢分离后经７个全国统一鉴别品种鉴定，共检出７群１５个小种。其中，ＺＧ１一直是江苏省的优势小种，ＺＤ，ＺＥ种群出现的频率也很高。各稻区小种分布不同，病害常年流行的太湖稻区种群最复杂。ＺＧ１小种能在大部分品种上分离到，且分离频率很高，ＺＤ和ＺＥ群小种也有较高的分离频率。根据各稻区小种分布，选育和引进相应的抗性品种非常迫切和重要。

摘 要：
monoconidial isolates were obtained from rice blast specimen collected from Jiangsu province during 1991～1996. The isolates were assessed on 7 Chinese differential varieties, and 7 groups and 15 races were identfied. Among them, ZG 1 was predominant and the ZD and ZE group also had high isolating frequence. There were different race distribution in different rice areas, and the most kinds of groups and races were in Taihu rice area. The race isolated from major varieties cultured in Jiangsu were analysed. Race ZG 1 was isolated on most of varieties with high isolating frequence. Therefore, it was important and urgent to breed or introdue resistant varieties against those high frequence races.
